METALLIC SHINGLE.

SPECIFICATION forming part of Letters Patent No. 297,530, dated April22, 1884.

Application filed October 24, 1883.

To all whom it may concern.-

Be it known that I, JOHN MoTT, a citizen of the United States, residingat New York city, in the county of New York and State of New Yorlghaveinvented certain new and useful Improvements in Metallic Shingles, ofwhich the following is a full, clear, and .exact description.

The object of this invention is to produce diamondshaped sheet-metalshingles for roofing purposes, which can be formed of square pieces ofmetal of such construction that the shingles of one course will overlapupon and cover the nail-holes in the course next below, and the pointsof each shingle will be held .down firmly, and so on throughout theextent of the roof.

Heretofore it has been found impracticable to use square metal shinglesfor roofing purposes of a construction adapted to be laid to form adiamond-shaped roofing with no exposed nail-holes, and withoutperpendicular joints, for the reason that the points of the shingleswould spring out of place, thereby leaving an opening for waterto enterbetween the courses. By my invention I am enabled to form diamond-shapedshingles out of square pieces of sheet metal adapted to be laid with auniform lap without perpendicular joints, and with the nail-holes in theshingles of one course covered by the shingles in'the course next above,and the points rigidly held down and precluded from springing out ofplace, whereby I economize in the quantity of material used both inmanufacturing the shingles and in covering a given area of surface, forthe reason that a square shingle can be cut to better advantage, and canbe laid to form an operative roofing with less lap than a shingle ofoblong or other form.

To enable others skilled in the art to make and use my invention, I willnow describe it by reference to the accompanying drawings, in whichFigure 1 is a plan view of one shingle embodying my improvements. ig. 2is a plan .view of four shingles in position as applied to a roof. Fig.3 is a cross-section taken on the line 00 m, Fig. 2; and Fig. 4 is adetail of an attaching-clasp for securing the points of the shingles inplace.

Each shingle is provided with a central lon- (No model.)

other and to the rib A, which extend across the shingle near thecorners. The lower end 'of each of these ribs 0 is provided with alongitudinal slot, 1). Between each rib O and the rib A the metal at thelower inclined edges of the shingle is stamped up to form a hollow rib,D; and E designates a slightly smaller rib stamped in the body of theshingle on each side of the rib A, and extending across the shingle in aline parallel with the upper inclined edges. On each side of the ribs 0,near their upper ends, are nail-holes c, and on each side of the rib A,near the upper end of the shingle, are nail-holes d. To secure theadjoining corners of two' shingles in the same course and the point ofthe overlapping shingle in the course next above in place, Iprefer toemploy an attaching-clasp of the construction shown by Fig. at of thedrawings, which clasp forms the subject-matter of an application forLetters Patent filed-by me on the 22d day of September, 1883, anddesignated as number 107,099, although any clasp suitable for thispurpose may be employed. The meth- 0d of laying these shingles is asfollows, viz: Commencing at the eaves-course, I employ shorts orhalfshingles, which consist of shingles with the lower ends cut off atthe line y 3 Fig. 1. These half-shingles are laid at the caves in asingle course, the ribs 0 of two adjoining shingles overlapping one uponthe other, so that the slots 1) are brought in a diroot line with eachother. The attaching-clasp V F is then inserted under the overlappingadjoining edges of the shingles, and its lip F projects upwardly throughthe slots 1). These half-shingles are then nailed to the roof at d d.The first course of full-sized shingles are then laid, the points Bbeing placed so that the rib A will overlap upon the ribs 0 of twoadjoining shingles in the course next below, and the slit (4 is broughtin line with the slots 12 of the shingles in the lower course, the ribs0 of each course as the shingles are laid overlapping, so as to bringthe slots 1) of adjoining shingles in' line with each other, as stated.The lip F of the clasp is then drawn up through the slit to, and bentover onto the IOO shingle, thus closing the slit, binding three shinglestogether, and holding the point B of the overlapping shingle firmly inplace. The attaching-clasps are inserted in place, as each course islaid, in the same manner as described in reference to the first course,excepting that in the second and succeeding courses thebody of the clasprests upon the underlying shingle, as shown by the section Fig. 3. Theribs 1) of the shingles of each course receive the ribs E in the twounderlying shingles which the point B rests upon. These ribs D E stiffenthe shingle, improve its appearance, and prevent water from bein gdriven upward between the courses. Each succeeding course of shinglcs islaid in the same manner as j ust described in reference to the firstcourse of fullsized shingles, the nail-holes c of the shingles in theupper course fitting over the nail-holes d in the shingles of the lowercourse, and the points of the overlapping shingles covering both sets ofnail-holes.

The ribs A G D E, in addition to the objects stated, also serve toprovide for contraction and expansion of the metal. If it is desired tomake the shingles present an architectural appearance when laid, anysuitable raised design may be stamped in the body of the shingle.

That I claim as my invention, and desire to secure by Letters Patent, is

1. A metallic roofing-shingle, substantially such as described, providedat its lower end, and just above the point, with a longitudinal slit. a,and at its parallel corners with longitudinal slots b b, as and for thepurposes set forth.

2. Metallic shingles of substantially the construction described, havinga longitudinal slit in the points and longitudinal slots in the oppositecorners, in combination with an at- (aching-clasp having a body adaptedto fit under the underlying shingles in the course next below, and anupwardly-projecting lip adapted to pass through said longitudinal slotsand slit, and be bent over onto the overlapping shingle, as and for thepurposes set forth.

3. Metallic shingles each having a rib, A, provided with a longitudinalslit, a, ribs C 0 parallel to each other and to the rib A, and eachprovided with a longitudinal slot, b, at their lower ends, and ribs D E,whereby dianiondshaped shingles may be formed out of square pieces ofsheet metal, and are adapted when combined with attaching-clasps to forma roofing, as set forth. y

In testimony whereof I have hereunto set my my hand.

JOHN MOTT.
